Stanadyne Diesel Fuel Additive Performance Formula — 16 oz bottles, Case of 12, injector cleaner & cetane boost

Stanadyne Performance Formula is a concentrated diesel fuel additive (16 oz bottle) designed to clean injectors, improve combustion, restore lubricity, and protect fuel systems when used year-round.

This case contains twelve 16-ounce bottles of Stanadyne Performance Formula, each treating up to 60 gallons of diesel fuel. The formula combines detergents, cetane improvers and lubricity agents to address common diesel fuel issues caused by low-sulfur fuels and deposit buildup. Use it routinely to help maintain engine responsiveness and reduce smoke and particulate output without altering engine design or OEM requirements where approvals exist.

How does this additive help restore lost engine power?

The Performance Formula contains targeted detergents that dissolve and remove varnish and carbon deposits from injectors and combustion chambers. Cleaner injectors deliver a finer, more consistent spray pattern, which helps the engine make better use of fuel and regain responsiveness.

• Detergent package removes injection-system deposits
• Improved spray atomization for consistent combustion
• Supports restored horsepower and smoother throttle response

Will it improve fuel economy and reduce emissions?

Laboratory and fleet tests show measurable fuel-economy gains when combustion efficiency and injector cleanliness are improved. The cetane-boosting components promote quicker ignition while lubricity additives reduce friction in precision fuel parts, which together can lower fuel consumption and visible smoke.

• Average MPG gains reported around 4 percent, with tests showing up to 9.6 percent
• Cetane improver for better ignition timing and reduced noise
• Lower smoke and particulate output from cleaner combustion

How does it protect fuel system components in modern low-sulfur diesel fuels?

Ultra-low sulfur diesel lacks natural lubricity, which can accelerate wear in pumps and injectors. Stanadyne Performance Formula restores lubricity and provides corrosion resistance to help lengthen the service life of fuel system components.

• Lubricity additives reduce wear on high-pressure pumps and injectors
• Corrosion inhibitors help protect metal surfaces in contact with fuel
• Compatible with modern diesel fuels and most engine OEM recommendations

Can I mix this with other Stanadyne products or use extra doses?

Stanadyne products are formulated to be blendable, and Performance Formula can be used alongside other Stanadyne additives without harm. Doubling doses won't damage the fuel system, though it typically won't provide twice the benefit; follow suggested treat rates for cost-effective results.

• All Stanadyne additives are blend-compatible
• Standard treat rate: one 16 oz bottle treats approximately 60 gallons
• Excess dosing is safe but usually unnecessary for normal maintenance

Who this product is for: fleet managers, diesel owners, and service shops seeking a year-round maintenance additive to clean injectors, improve fuel economy, restore lubricity to ultra-low sulfur fuels, and reduce visible emissions. It’s suitable for light- and heavy-duty diesel applications where Stanadyne Performance Formula is accepted by the OEM, and for anyone wanting a maintenance regimen that helps protect fuel system components and sustain engine performance.
